Tailored emission enhancement of extended phosphor layers by nanostructured surfaces

摘要

Arrays of plasmonic nanoparticles covered by polymer layers containing fluorescent molecules support collective photonic-plasmonic modes. These modes have non-homogeneous electric field distributions, which have a strong impact on the emission. In this presentation we investigate the enhancement of the coupling between collective modes and luminescent molecules by improving the spatial overlap between the emitters and the mode field profile.
